Statistics bureau says 15% drop. Your house requires 30% off.
Statistical price ≠ real transaction price. Fdamage theory gives closer-to-real decline estimates.
Can't see the truth
Official index says slight drop, second-hand actual transactions drop deeply.
Agent rhetoric
Regional transaction prices hidden, information asymmetry worsens.
No basis for decisions
Buying/selling property lacks a reference real price report.
METHODOLOGY
ExploratoryCorrection Methodology (Public Version)
Multipliers provided are rough estimates based on experience, not precise price predictions. Like statistics bureau publishes revised data, these multipliers may be revised.
Low Correction
1.5×
Reference from exchange rate slightly deviating from PPP. Applies to cities with active transactions and smooth price discovery.
High Correction
3×
Reference from exchange rate moderately deviating from PPP. Applies to cities with purchase/sale restrictions and guided prices.
Monthly correction MoM = Official MoM × Distortion multiplier
Correction index = ∏(1 + Monthly correction MoM)
